Answer:
C) f(x) increases by 900%
Step-by-step explanation:
The rate of change is
f(4) - f(3)
---------------
4-3
f(4) = 9*4 = 36
f(3) = 9*3 = 27
36 -27
---------------
4-3
9
-----
1
The rate of change is 9
To change to a percent, multiply by 100%
9*100% = 900%
In a meter there are 100 cm.
In 100 cm there are 1000 mm.
Therefore in 1 meter you have 1000 millimeters.
Then to find out how many millimeters you have in 14 meters, you just multiply 14 by 1000 to give you 14000 mm.
Final answer= 14 m of gold wire is the equivalent to 14000 mm of wire.
